Jackson described as 'loopy' after doctor visits

FILE - In this March 5, 2009 file photo, Michael Jackson announces several concerts at the London O2 Arena in July, at a press conference at the London O2 Arena. Stacy Walker, a choreographer who worked with Jackson in his ill-fated “This Is It” shows, told a civil jury in a Los Angeles courtroom on Monday May 13, 2013, that she did not see any signs that the singer was ill or might die in his final days and weeks. Walker is AEG’s first defense witness in a civil case filed by Jackson’s mother, Katherine Jackson, who claims the concert giant failed to properly investigate or supervise the doctor convicted in 2011 of causing the singer’s death.
